About this file
This document contains specifications for an Active Electronically Scanned Array (AESA) antenna and a related sources sought notice. The Naval Research Laboratory requires an AESA antenna meeting detailed technical specifications, including transmitting and receiving channels, gain, power, bandwidth, scan angles, accuracy, polarization, and environmental tolerances. Interested parties must provide capability statements responding to the specifications by listing relevant capabilities and resources, addressing the commerciality of any proposed item, and describing how their product would meet or exceed each specification. They must also indicate if their products are available through multiple award schedules. The Government intends to award a contract to build, test, deliver, and provide interface documents for the AESA antenna within 12 months of contract award.
